Ingredients
Vegetables & Aromatics
- 3 medium leeks (tops removed, cut in half and thinly sliced)
- 8 ounces oyster mushrooms
- 4 garlic cloves (minced)
- 2 sage leaves
- 1 teaspoon lemon zest
Liquids & Dairy
- 2 tablespoons olive oil
- 3 tablespoons butter (divided)
- 1/3 cup sherry wine
- 3/4 cup heavy cream
- 1 tablespoon balsamic vinegar
- 1/2 cup grated Gruyere cheese
Pantry Items & Seasonings
- 1/2 teaspoon salt (plus additional for seasoning)
- 1/2 teaspoon granulated sugar
- 1 teaspoon black pepper (plus additional for seasoning)
- 1 lb fettuccine
- 1 cup reserved pasta water
- 1/4 cup toasted pine nuts
Instructions
- Caramelize the Leeks: Heat 2 tablespoons olive oil and 2 tablespoons butter in a large sauté pan over medium heat. Add the sliced leeks, season with 1/2 teaspoon salt and 1/2 teaspoon granulated sugar, and cook until golden and caramelized, about 20 minutes, stirring occasionally. Add 1-2 tablespoons of water if the pan becomes too dry to prevent burning.
- Deglaze with Sherry: Pour in 1/3 cup sherry wine and cook until the wine has reduced. Remove the caramelized leeks from the pan and set them aside.
- Brown the Mushrooms: In the same pan, melt the remaining 1 tablespoon butter. Spread the oyster mushrooms in an even layer, ensuring they have space between them. Let them cook undisturbed until browned, about 4 minutes, then flip and brown the other side. Season with salt and pepper.
- Sauté Garlic and Sage: Add the minced garlic and sage leaves to the mushrooms and sauté for 1 minute until fragrant. Return the caramelized leeks to the pan, then add 3/4 cup heavy cream, 1 tablespoon balsamic vinegar, and 1 teaspoon lemon zest. Bring to a simmer and cook until thickened, approximately 2-3 minutes. Adjust seasoning with salt and pepper.
- Cook the Pasta: Meanwhile, cook 1 lb fettuccine in salted boiling water until al dente. Reserve 1 cup of the pasta cooking water before draining the pasta.
- Combine Pasta and Sauce: Add the drained fettuccine to the sauce along with 1 cup reserved pasta water, 1/2 cup grated Gruyere cheese, and 1 teaspoon black pepper. Toss well to coat the pasta evenly and simmer for 2 minutes or until the cheese has melted and the sauce is creamy. Adjust seasoning with salt and pepper as needed.
- Serve: Divide the pasta among 4 bowls and garnish each with 1/4 cup toasted pine nuts. Serve immediately while warm.
Notes
- To caramelize leeks evenly, slice them thin and stir occasionally to prevent burning.
- If sherry wine is unavailable, dry white wine or vermouth can be substituted.
- For a nuttier flavor, consider lightly toasting the pine nuts yourself before garnishing.
- Reserve some pasta water to adjust sauce consistency if it becomes too thick.
- This recipe can be prepared with gluten-free pasta for a gluten-free option.
